Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.

Where the curve breaks

The frontier is gentle until it isn't. Going from Zagora (595 kg, 32.1 °C) to Dayrut (901 kg, 33.3 °C) buys 1.2 °C more warmth for an extra 306 kg — 255 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.
